. JULIUS E. KbBERNIK, DE LOS ANGELES, CALIFORNIA BUBBLE car Application filed January 5, 1928. Serial No. 244,615.

My invention relates to a bubble cap for use 1n apparatus for treating'hydrocarbons in which apparatus absorbing, distilling, fractioning or stabilizing operations are carried on, especially in the production of motor fuel. In the apparatus of the class referred to, a gas or vapor is caused to pass upwardly through the apparatus, and in its upward passage is repeatedly brought in contact with 1 a liquid h drocarbon passing in the opposite direction y gravity, 1

One of the features of such apparatus is to cause a most intimate and repeated contact between the gases or vapors, and the hydrocarbon liquid under treatment. Such apparatus usually contains a series of mixing or reaction chambers vertically arranged one above the other. The partitions separating the chambers are perforated and over these perforations a so-called bubble cap is disposed, the object of such bubble caps being .to divide into fine bubbles the ascending gases or vapors and to thoroughly mix such bubbles of as and vapors with the liquid 2 in which t e 'bu'bble caps are immersed.

Such apparatus has provisions for submergin the bubble caps to a predetermined depth.

he present invention relates to a bubble cap, and it is an object of the invention to provide a simple and highly eflicient structure .easily made and installed.

My invention consists in the construction and arrangement of parts hereinafter described and claimed.

Referring to the accompanying drawings which form a' part of this specification.

Figure 1 shows a fragmentary .view partly in section, of an apparatus for treating hydrocarbons such for instance, as disclosed in my U. S.,Patent No. 1,613,352, of January Figure 2 is a Vertical cross section of my bubble cap positioned over a perforation of a artition. v

igure 3 is a side elevation of the bubble cap shown in Figure 2. Figure 4 is a top plan view thereof. 1 Figure 5- shows the blank of metal of which the bubble cap is formed. U The particular type of apparatus as'stated ber 3 immediately below; 6 indicates the partition separating the chambers 2 and 3, the partition being rovided with perforations 7 over which bu ble caps 8 constituting the object of my invention are disposed.

The bubble cap 8 is formed out of a sheet of metal shown in Figure 5, which consists of a circular top portion 9 and a pair of leg portions 10 integral with the top and dia- 7 metrically disposed. Thetop portion 9 is preferably dished or convex, as shown in Figures 2 and 3, and rovided with perforations 11. The perip cry of the top port1on 9 is serrated at 12. The leg portions 7 10 are bent at right angles downwardly from the top portion 9 and are placed equidistantly and in alignment with perforations 7 of the partition 6 and preferably secured thereto y spot welding as indicated at 13.

In the operation of the device, the hydrocarbon gases and vapors pass upwardly from chamber 3 to chamber 2 through perforations 7, the pressure of the gas or vapor being such as to prevent any appreciable amount of the 35 hydrocarbon liquid in chamber 2 from escaping back through perforations 7 into chamber 3. The bubbles of as and vapor in the upward movement, stri e' against the dished perforated top portion 9 of the bubble cap, and are divided into small bubbles in passing therethrough. If a pressure builds up below the top portion 9 and the gas passes the periphery of the same, owing to the serratio 12, the gas will be divided into fine bubbles, the result being a violent boiling action about each bubble ca effecting a most intimate mixture between t e gas and vapor and the liquid hydrocarbon.

While the bubble cap described is especially intended for use in hydrocarbon treatment apparatus it will be understood that its use is not limited thereto, but may be employed in any apparatus where any gas or vapor is made to contact with a liquid.

Various changes in the construction and arrangement of parts may be made by those skilled in'the art, without departing from the spirit of the invention as claimed. I claim:

1. A bubble cap of the class described, made of a single sheet of metal having a pair of uprights diametrically arranged and extending from a perforated, circular, convex' to A bubble cap of the class described, made of a sin 1e sheet of metal having a pair of uprights iametrically arranged and extending-from a perforated, circular, convex top, the periphery of said top being serrated.

In testimony whereof I have signed m name to this specification.
